Abstract
a coaster brake (16) articulated to the support (6), pivotable by the cam portion (14) of the pedal (10) as a result of the pivoting thereof, and having a portion (20) which is arranged to interfere with the wheels (4) as a result of its pivoting in order to stop the wheels (4). The brake also includes a resilient element (22) which, in the rest position, keeps the coaster brake (16) spaced from the wheels (4), and
a small pedal (26) which, in the rest position, is inserted in a seat (24) within the support (6) and which has an operating portion (27) and a slot (28) in which the hook-shaped end (30) of the control portion (14) of the pedal (10) is inserted. The operation of the pedal (10) causes the removal of the small pedal (26) from its seat (24), whilst the operation of the operating portion (27) of the small pedal (26) causes the reinsertion of the small pedal (26) in its seat (24) and the pivoting of the pedal (10) into its rest position, with the consequent release of the coaster brake (16) from the wheels (4).
Description
- The present invention relates to a parking brake for twin wheels cantilevered rotatably on a support member. The brake is characterised in that it comprises:
a forked support member,
a pedal with an operating portion projecting from the support and a cam-shaped drive portion located within the support, the pedal being pivotable between a rest position and an operative position,
a coaster brake articulated on the support and pivotable by the cam of the pedal as a result of the pivoting thereof, the brake having a portion which is arranged to interfere with the wheels as a result of its pivoting in order to stop the wheels,
a resilient element which, in the rest position, keeps the coaster brake spaced from the wheels, and
a small pedal which, in the rest condition, is inserted in a seat within the support and which has an operating portion and a slot, in which the hook-shaped end of the drive portion of the pedal is inserted, the operation of the pedal causing the removal of the small pedal from its seat and the operation of the operating portion of the small pedal causing the reinsertion of the small pedal in its seat and the pivoting of the pedal into its rest position with the consequent release of the coaster brake from the wheels. - The object of the present invention is to provide a parking brake for a pair of twin wheels which is simple to produce and easy to operate.
- The advantages and characteristics of the present invention will become clear from the following detailed description, given with reference to the appended drawings, provided by way of non-limiting example, in which:
- Figure 1 is a perspective view of a parking brake according to the invention in the rest position and mounted on a pair of twin wheels of a trolley,
- Figure 2 is a perspective view of the brake of Figure 1 in the operative position,
- Figure 3 is a section taken on the line III-III of Figure 1, and
- Figure 4 is a perspective view of the brake according to the invention.
- With reference to the drawings, a trolley 2 has a pair of
twin wheels 4 cantilevered rotatably on asupport member 3 having avertical portion 5 and ahorizontal portion 7 coaxial with theaxle 8 of thewheels 4. - A parking brake for the
wheels 4 includes a forkedsupport member 6 constituted by across-member 6a from beneath which project twoarms 6b which haveholes 9 for receiving theportion 7 of thesupport member 3. A pair of facing, aperturedprojections 11 is formed around thehole 9 of at least one of thearms 6b for the insertion of aresilient pin 13 for fixing thefork 6 to thehorizontal portion 7 of thesupport member 3 in a position in which it is inclined to the vertical. - The parking brake further includes a
pedal 10 having anoperating portion 12 projecting from thesupport 6 near thecross-member 6a and a cam-shaped drive portion 14 within thesupport 6. Thepedal 10 can pivot between a rest position (shown in Figure 1) and an operating position (shown in Figure 2). - A
coaster brake 16 which is articulated, or at any rate pivoted at 15, on thesupport 6, is pivotable by thecam portion 14 of thepedal 10 and has twoarms 18 which extend outside thesupport 6, parallel to theaxle 8, for interfering with thewheels 4 so as to lock them as a result of the pivoting of the coaster brake. The regions of thearms 18 which will come into contact with thewheels 4 may havelinings 20 of anti-friction material. Awire spring 22 keeps thearms 18 of thebrake 16 spaced from thewheels 4 in the rest condition of the brake. In alternative embodiments of the invention, not illustrated, it is possible to use a leaf spring instead of thewire spring 22. - The
support 6 has aseat 24 in which asmall pedal 26 is inserted when the brake is in the rest condition, thesmall pedal 26 having an aperatingportion 27 and aslot 28 in which a hook-shaped end 30 of thedrive portion 14 of thepedal 10 is inserted. - To change from the rest configuration (shown in Figure 1) to the braking configuration (shown in Figure 2), it is necessary to pivot the
pedal 10 by acting on itsoperating portion 12. The cam-shaped portion 14 of thepedal 10 thus makes thecoaster brake 16 pivot about thehinge 15 to bring theanti-friction linings 20 of thearms 18 into contact with thewheels 4 and thus stop them. As thepedal 10 pivots, the hook-shaped end 30 simultaneously moves thesmall pedal 26 out of itsseat 24. - In order to return from the braking configuration to the rest configuration, it suffices to act on the
operating portion 27 of thesmall pedal 26 to return it, by a translational movement, into itsseat 24. During this movement, thepedal 10 pivots in the opposite sense from its previous pivoting as a result of the engagement between its hook-shaped end 30 and theslot 28 in thesmall pedal 26, and releases thecoaster brake 16 which returns to the rest position under the action of thespring 22, releasing thewheels 4.
Claims (6)
a forked support member (6),
a pedal (10) with an operating portion (12) projecting from the support (6) and a cam-shaped drive portion (14) located within the support (6), the pedal (10) being pivotable between a rest position and an operative position,

a resilient element (22) which, in the rest position, keeps the coaster brake (16) spaced from the wheels (4), and
a small pedal (26) which, in the rest condition, is inserted in a seat (24) within the support (6) and which has an operating portion (27) and a slot (28) in which the hook-shaped end (30) of the drive portion (14) of the pedal (10) is inserted, the operation of the pedal (10) causing the removal of the small pedal (26) from its seat (24) and the operation of the operating portion (27) of the small pedal (26) causing the reinsertion of the small pedal (26) in its seat (24) and the pivoting of the pedal (10) into its rest position with the consequent release of the coaster brake (16) from the wheels (4).
the brake being characterised in that the forked support member (6) is constituted by a cross-member (6a) from beneath which extend two arms (6b) which have respective holes (9) for receiving the horizontal portion (7), a pair of facing, apertured projections (11) being formed around at least one of the holes (9) for the insertion of a resilient pin (13) for fixing the support (6) to the horizontal portion (7) of the support member (3) in a position in which it is inclined to the vertical.
